It is widely used in aerospace, petrochemical, machinery manufacturing, vehicle manufacturing, wire and cable, textile fiber, plastic rubber, ceramics. Building materials, food, pharmaceutical packaging, metal materials, construction engineering and other industries, as well as institutions of higher learning, research institutes, technical supervision, quality inspection stations, etc.; can be stretched according to GB, ISO, ASTM, JIS, DIN and other standards , compression, bending, peeling, shearing, tearing, puncture, bursting and various high and low temperature tests, can detect the yield strength, tensile (pressure, bending) strength, elongation, tensile strength, non-material Proportional strength, elastic modulus and other parameters.
2. Function introduction of 20KN Computer Control Universal Tensile Testing Machine
a) AC servo motor is adopted, which has stable and reliable performance and has protection devices such as overcurrent, overvoltage, overspeed and overload. The speed ratio can reach 1:100,000.
b) The electrical control circuit refers to the international standard, conforms to the national test machine electrical standard, and has strong anti-interference ability, which ensures the stability of the controller and the accuracy of the experimental data.
c) Automatic shifting: automatically switch to the appropriate range according to the load size to ensure the accuracy of the measured data; realize the automatic shifting, zeroing, calibration and real-time physical zero adjustment, gain adjustment and test force measurement Save the disk without any analog adjustment link, the control circuit is highly integrated
d) Condition storage: The test control data and sample conditions can be made into modules, which facilitates the batch test;
e) Automatic shifting: the speed of the moving beam during the test can be changed automatically according to a preset program, or can be changed manually;
f) Automatic calibration: the system can automatically realize the calibration of the indication accuracy;
g) automatic saving: the test is over, the test data and curve are automatically saved;
h) Process realization: the test process, measurement, display and analysis are all completed by the microcomputer;
i) Batch test: samples of the same parameters can be completed in sequence after one setting;
j) Test software: menu prompt, mouse operation;
k) Display mode: data and curves are dynamically displayed with the test process;
l) Curve traversal: After the test is completed, the curve can be re-analyzed, and the test data corresponding to any point on the curve can be found with the mouse;
m) Curve selection: The stress-strain, force-displacement, force-time, displacement-time curves can be selected for display and printing;
n) Test report: Reports can be prepared and printed according to the format required by the user; with network interface, data transmission, storage, print recording and network transmission printing can be performed, and can be connected with the internal office or Internet of the enterprise.
o) Limit protection: with program-controlled and mechanical two-level limit protection;
p) automatic stop: after the sample breaks, the moving beam automatically stops;
q) Overload protection: When the load exceeds 3-5% of the maximum value of each gear, it will automatically stop;
Both automatic and manual modes are used to obtain test results, and reports are automatically generated to make the data analysis process simple.
